Y is obtained form x by multiplying x by -1/3.
so when x = -3 y = -3 * -1/3 = 3/3 = 1
when y = 0, 0 = x * -1/3 so x = 0
so b) is the correct choice.
Answer:
-3/4
Step-by-step explanation:
y2-y1/x2-x1 =
-1-2/4-0=
-3/4
Answer:
(2, -2)
Step-by-step explanation:
First, you make 2 equations.
-6 + x = -4 (The -6 is from point A and the -4 is from point M)
3 + y = 1 (The 3 is from point A and the 1 is from point M)
Then you subtract -6 from each side of the first equation and subtract 3 from each side of the second equation.
You should get:
x = 2
y = -2
Answer:
For matrix multiplication to work, the columns of the second matrix have to have the same number of entries as do the rows of the first matrix. ... In particular, matrix multiplication is not "commutative"; you cannot switch the order of the factors and expect to end up with the same result.
